P' 'tenterl L Application filed February is, 1910. Serial 1-10. ra-z.

Washington, have invented certain new and" useful Improvements inInsulated Hangers; and I do hereby declare the following to be a full,clear, and, exact description of the invention, such as will enableothers skilled in the art to which it appertains to make 'and use thesame.

' In the stringing of electrioconductors, such as telephone wires, etc,it has been customary to secure the conductor to a sup porting member bymeans of a short piece of wire or to twist the conducting wire aroundthe support in order to insure its retention. Thiscauses much annoyancebecause ofthe snapping-of the wires at the binding point under thepressure of wind or ice, there being insufiioient play allowed the wiresto withstand such weight.

It is the object of my invention to over come this trouble and to thisend I provide a hanger which while afiording the neces sary support forthe wire will prevent strain thereupon and one which may be turned inany desired direction relatively to its support without danger oftwisting or crimp- 111% or otherwise injuring the wire.

:1 thc'accornpanying drawings, Figure l.

is a view in perspective showing the support attached to the side of awall. Fig. 2 shows the support adapted for a turn of the wire. Fig. 3 isa sectional view.

Referring to the drawings, 1 designates block of insulating material,such as porcelain, and 2 a yoke, the spaced-apart ends of which areembedded in the block. In the periphery of the block a circumierenti lgroove 3 is formed to accommodate telegraph or telephone wires andprevent lateral displacement thereof. The yoke spans the groove.

The hanger to any suitable support by means of a hook of peculiarconstruction by means oi which it may he so positioned as to allow wiresto he strung at different angles without danger oi? undue twisting orcrowding the blocks from their supports. The eye portion 6 of the in theform of an involute spiral, is

of such length as to provide considerable overlap. The space between theoverlapping portions is 'suilicient to allow of the free passage of theyoke, and hen ce the block may be readily secured to the eye and at thesame time it can be turned on almost a complete circle, with the eye oithe screw as a pivot. Itmay occupy a horizontal position, as shown in l.and 8, or verticel position as indicated in Fig. 2.

I claim as my invention:

1. A hanger or support for el ctric wires comprising a block having acircumferential groove, a yoke projecting from said block and spanningsaid groove, and a support having an involute spiral with which saidyoke is designed to engage.

2. A hanger or support for electric wires com risin a block, circular incross section, having a circumferential groove, a yoke pro jecting fromsaid block and spanning said groove, and a screw eye in the form of aninvolute spiral with which said yoke is designed to engage.

In testimony whereof, l have signed this specification in the "presenceof twe subscribing witnesses.
